Rotary Kiln Supporting Roller Specification
- Materials: ZG55, ZG42CrMo, etc
- Processing weight: ≤50t
- Certification: ISO, SGS
- Application industry: cement, chemical machinery
Kiln supporting roller is the main component of rotary kiln. The kiln support roller bears the weight of the entire rotating part and plays a directional effect on the cylinder so that the cylinder and the rotary kiln tyre can rotate smoothly on the kiln supporting roller. When installing the rotary kiln, you should choose high-quality kiln supporting rollers, which can effectively prolong the service life of the rotary kiln and reduce the maintenance cost of the rotary kiln accessories.

AGICO has many years of experience in processing and manufacturing rotary kiln accessories and large steel casting workshops and has mature technological advantages in casting rotary kiln tires, large gear rings, kiln supporting rollers, thrust rollers, and other accessories. The kiln support rollers produced by AGICO mainly include rotary kiln supporting rollers and cast steel supporting rollers, which can also be customized according to customers’ drawings.
The Kiln Supporting Roller Produced by AGICO is More Competitive
High-quality steel, more load-bearing
The supporting rollers are mostly made of ZG55, ZG42CrMo, and other high-quality materials. The produced Kiln supporting rollers can carry a large load, and have strong impact resistance, high hardness, and wear resistance.


Simple process and low maintenance cost
AGICO steel casting kiln supporting roller to use rolling bearing wheelsets, which run smoothly, and the manufacturing precision of rolling bearings is high. Compared with rotary kilns using sliding bearings, rolling bearings run more smoothly and maintenance is relatively reduced.
More professional heat treatment process and the guaranteed kiln support roller hardness
AGICO uses normalizing and tempering processes in the casting process of the supporting roller so that the surface hardness of the cast steel supporting roller is higher than 200HB. Thereby, better high-temperature resistance performance and smaller friction resistance are obtained, which ensures the quality of the rotary kiln supporting roller.
